Sweave makes a lot of use of verbatim environments, and beamer doesn't 
like those.  You need to declare that a slide contains verbatim or you 
get errors like that.

I'm sure there are other ways to do this, but one that works is to use

\begin{frame}[containsverbatim]

at the start of each slide.  This makes some other beamer features stop 
working, but I forget which.
